Introduction Nutrition plays a pivotal role in life and in medicine. Acute and chronic diseases in most organ systems have pronounced effects on food intake and metabolismwith increased catabolism, which lead to nutrition-related conditions associated with increasedmorbidity and eventually death. At the other end of the spectrum, diet is a major determinant of future health, i.e. the absence or post- ponement of disorders like cardio-vascular disease, diabetes, can- cer and cognitive disease [1]. In order to handle nutritional challenges during disease, trauma, rehabilitation, and elderly care as well as for the nutritional pre- vention of disease it is essential to use professional language and standard terminology that is founded on evidence and widely accepted in the professional community. However, this is not al- ways the case. For example, concepts and terms of nutritional disorders in the current International Classifications of Diseases (ICD-10) (http://www.who.int/classifications/icd/en/) may not al- ways be consistent with modern understanding or terms commonly used in clinical practice and research. Therefore, it is important for the nutritional practice and research communities, including dietitians, nurses, pharmacists, physicians and scientists as well as their respective scientific as- Consensus Malnutrition Clinical nutrition Medical nutrition Results: Five key areas rela delivery; and products.

The presented Guideline standard operating pro- cedures (SOP) aimed to generate high quality guidelines using a clear and straight-forward consensus procedure, with one of the goals to establish international leadership in creating up-to-date and suitable-for-implementation guidelines. To provide a termi- nology basis for the guideline development was one of the reasons for launching this initiative. An international expert group of experienced clinical scientists was compiled to form the Terminology Consensus Group and to undertake a modified Delphi process. The consensus group par- ticipants, i.e. the authors, were selected to represent various clinical nutrition fields, as well as various professions; dietitians, nurses, nutritionists, pharmacists and physicians from clinical and basic science. It was agreed within the group to base the process on open e-mail communications, face-to-facemeetings and open and closed ballots. The purpose was to ensure that communication was maintained at each milestone (see below) until a consensus was reached among all participants. Thus, the statements are based on consensus rather than on systematic literature searches. This ESPEN Consensus Statement is partly based on the 2014 initiative by the German Society of Nutritional Medicine Working Group (DGEM WG) and the related publication “Suggestions for terminology in clinical nutrition” [3]. The WG consisted of dele- to clinical nutrition were identified: concepts; procedures; organisation; ore concept of clinical nutrition is malnutrition/undernutrition, which in- rition (DRM) with (eq. cachexia) and without inflammation, and malnu- disease, e.g. hunger-related malnutrition.

Moreover, we did not indicate levels of evidence for the statements, because for most issues clinical trials are lacking. However, we indicate the strength of consensus according to the ESPEN classi- fication (Table 1). Final consensus beyond the working group was achieved by a Delphi round using an electronic platform and offering five voting options (agree, rather agree, indecisive, rather disagree, disagree) and the possibility to place individual comments. Apart from the guideline authors, other ESPEN members were invited to partici- pate within four weeks. A total of 38 experts took part and voted and provided comments. The main text was divided into 90 para- graphs open for voting. The voting results are indicated in the text using the classification of Table 1 and the exact percentage of agreement (sum of ‘agree’ and ‘rather agree’). 2.3. Map of nutritional terminology A decision was taken to organize the terminology base into five categories as described in Table 2. 3. Results 3.1. Nutritional concepts Nutrition science deals with all aspects of the interaction be- tween food and nutrients, life, health and disease, and the pro- cesses by which an organism ingests, absorbs, transports, utilizes and excretes food substances [4]. [Strong Consensus, 97% agreement] Human nutrition addresses the interplay of nutrition in humans. Preventive nutrition addresses how food intake and nutrients may affect the risk of developing disease such as cardiovascular disease (CVD), obesity, type 2 diabetes mellitus (T2DM), dementia and cancer, either for populations or for individuals. Public health nutrition targets actions on a population level in order to reduce the nutrition related major non-communicable diseases (some mentioned above) (Table 3). [Strong Consensus, 95% agreement] Clinical nutrition is the focus of the present terminology consensus initiative, which is the discipline that deals with the prevention, diagnosis and management of nutritional and meta- bolic changes related to acute and chronic diseases and conditions caused by a lack or excess of energy and nutrients. Any nutritional measure, preventive or curative, targeting individual patients is clinical nutrition. Clinical nutrition is largely defined by the inter- action between food deprivation and catabolic processes related to disease and ageing (Table 4, Fig. 2). Clinical nutrition includes the nutritional care of subjects with CVD, obesity, T2DM, dyslipidae- mias, food allergies, intolerances, inborn errors of metabolism as well as any disease where nutrition plays a role such as cancer, stroke, cystic fibrosis and many more. Furthermore, clinical Table 1 Classification of the strength of consensus. Strong consensus Agreement of >90% of the participants Consensus Agreement of >75e90% of the participants Majority agreement Agreement of >50e75% of the participants No consensus Agreement of <50% of the participants nutrition encompasses the knowledge and science about body composition and metabolic disturbances that cause abnormal changes in body composition and function during acute and chronic disease. [Consensus, 89% agreement] Malnutrition/undernutrition, overweight, obesity,micro- nutrient abnormalities and re-feeding syndrome are clear nutri- tional disorders, whereas sarcopenia and frailty are nutrition related conditions with complex and multiple pathogenic back- grounds (Table 4, Fig. 1). 3.2. Clinical nutrition 3.2.1. Malnutrition. Synonym: undernutrition Malnutrition can be defined as “a state resulting from lack of intake or uptake of nutrition that leads to altered body composition (decreased fat free mass) and body cell mass leading to diminished physical and mental function and impaired clinical outcome from disease” [5]. Malnutrition can result from starvation, disease or advanced ageing (e.g. >80 years), alone or in combination [6]. Basic diagnostic criteria for malnutrition have been defined by an ESPEN Consensus Statement [7]. Those general criteria are intended to be applied independent of clinical setting and aeti- ology. A similar approach to define diagnostic criteria has been described by a working group of the American Society of Parenteral and Enteral Nutrition (ASPEN) and the Academy of Nutrition and Dietetics (Academy) [8]. For details, see respective papers. [Consensus, 82% agreement] Briefly, the ESPEN criteria [7] could be summarized that prior to the diagnosis of malnutrition the criteria for being “at nutritional risk” according to any validated nutritional risk screening tool must be fulfilled. Any of two alternative sets of diagnostic criteria will confirm the diagnosis; i.e. either reduced body mass index (BMI) <18.5 kg/m2 in accordance with the underweight definition pro- vided by WHO, or combined weight loss and reduced BMI (age- dependent cut-offs) or reduced gender-dependent fat free mass index (FFMI). Similarly a brief summary of the ASPEN and Academy [8] criteria for malnutrition is that six malnutrition criteria need to be considered for the potential diagnosis of malnutrition; i.e. low energy intake, weight loss, loss of muscle mass, loss of subcu- taneous fat, fluid accumulation, and hand grip strength, whereof at least two should be fulfilled for the diagnosis of malnutrition. There is an obvious need for the global nutrition community to come together and find a consensus on the crucial issue of which criteria to use for the malnutrition diagnosis [9]. [Consensus, 85% agreement] Subordinate to the general diagnosis of malnutrition are the aetiology-based types of malnutrition. Table 4 and Fig. 2 describe and depict disease-related malnutrition with or without inflam- mation, and malnutrition/undernutrition without disease. Sub- classifications of malnutrition are crucial for the understanding of the related complexities and for planning treatment. [Consensus, 85% agreement] 3.2.1.1. Disease-related malnutrition (DRM) with inflammation. DRM is a specific type of malnutrition caused by a concomitant disease. Inflammation is an important watershed for malnutrition aetiology [8,10e12]. Thus, one type of DRM is triggered by a disease-specific inflammatory response, whereas the other is linked mainly to non-inflammatory etiologic mechanisms. [Strong Consensus, 97% agreement] DRM with inflammation is a catabolic condition characterized by an inflammatory response, including anorexia and tissue breakdown, elicited by an underlying disease. The inflammation utrition 36 (2017) 49e64 51 triggering factors are disease specific, whereas the inflammatory A special concern is that malnutrition is an emerging occurrence Table 2 Taxonomy of nutrition terminology, i.e. the structure of nutritional nomenclature as presented in this consensus statement.

The degree of metabolic response induced by the disease de- termines the catabolic rate and at what point during the disease trajectory when clinically relevant malnutrition occurs. The role of inflammation in the development of malnutrition is emphasized in a non-diagnostic definition, i.e. “malnutrition is a subacute or chronic state in which a combination of negative energy balance and varying degrees of inflammatory activity has led to changed body composition, diminished function and adverse outcomes” [5,11]. Advanced ageing per se may contribute to the state of inflammation [13]. Moreover, inactivity and bed rest accelerate muscle catabolism during DRM with inflammation.

Overview of nutrition disorders among overweight/obese persons with disease, injury, or high energy poor quality diets in both developed and developing countries. The underlying general mechanism is a misbalance be- tween the energy intake, energy expenditure and the quality of the nutrient intake. Fat mass/adipocytes in excess, especially in the form of central obesity, are associated with an inflammatory response that also likely contributes to the state of malnutrition (see also Section 3.2.4.1.1). Subordinate concepts to DRM with inflammation are; - chronic DRM with a milder inflammatory response, and; - acute disease- or injury-related malnutrition that is character- ized by a strong inflammatory response (Table 4, Fig. 2) [8,10e12,14]. [Strong Consensus, 100% agreement] 3.2.1.1.1. Chronic DRM with inflammation. Synonym: cachexia. The two concepts of chronic DRM with inflammation and cachexia are exchangeable, although cachexia is often incorrectly perceived as end-stage malnutrition. Cachexia is traditionally described as “a complex metabolic syndrome associated with underlying illness and characterized by loss of muscle mass with or without loss of fat mass. The prominent feature of cachexia is weight loss in adults” [15,16]. The cachectic phenotype is characterized by weight loss, reduced BMI and reduced muscle mass and function in combina- tionwith an underlying disease that displays biochemical indices of on-going elevated inflammatory activity. Cachexia occurs frequently in patients with end-stage organ diseases that are complicated by catabolic inflammatory responses, which include cancer, chronic obstructive pulmonary disease (COPD), inflamma- tory bowel diseases, congestive heart failure, chronic kidney dis- ease and other end-stage organ diseases. The systemic inflammation that drives the catabolism of such disorders is usually of milder character; i.e. for example serum concentrations of C-reactive proteins (CRP) seldom exceed 40 mg/L, although inflam- matory flaresmay occur during disease exacerbations. CRP >5mg/L is suggested as a lower limit to define relevant inflammation in this scenario; although other CRP cut-off levels for various given methods, as well as other biochemical inflammatory markers, could be considered. Cachexia, as described in cancer, can progressively develop through various stages: pre-cachexia; cachexia; and refractory cachexia [16,17]. Cancer cachexia, which is a specific form of chronic DRM with inflammation, is according to Fearon et al. [17] defined by either weight loss >5% alone, or weight loss >2% if BMI is and nutrition-related conditions. non-inflammation related mechanisms. Inflammation may for ition al N reduced (<20 kg/m2) or fat free mass (FFM) is reduced; i.e. appendicular skeletal muscle mass index <7.2 kg/m2 (men) or <5.5 kg/m2 (women). [Strong Consensus, 93% agreement] A similar concept known as cardiac cachexia has been estab- lished by Anker et al. [18] for patients with chronic heart failure which is based on non-intentional and non-oedematous weight loss >7.5% of the premorbid normal weight. Cardiac cachexia is associated with abnormal neuroendocrine and immunologic function and impaired prognosis independent of age and severity of disease. Patients with pre-cachexia are at risk of malnutrition due to the inflammatory response elicited by the underlying chronic disease [16,17] (see Section 3.3.1.1). Diagnostic criteria for chronic DRMwith inflammation/cachexia are suggested to be the same as those for malnutrition combined with the simultaneous presence of an underlying disease and biochemical indices of either ongoing or recurrent inflammation. Biochemical indicators of inflammation include elevated serum CRP concentrations and/or reduced serum concentrations of albu- min. [Strong Consensus, 97% agreement] 3.2.1.1.2. Acute disease- or injury-related malnutrition. Patients in an Intensive Care Unit (ICU) with acute disease or trauma (e.g. major infections, burns, closed head injury) or those after major surgical procedures display specific nutritional chal- lenges with high risk of consequent malnutrition due to their often Fig. 2. Diagnoses tree of malnutrition; from at risk for malnutr T. Cederholm et al. / Clinic highly pronounced stress metabolism [14]. The combined action of high pro-inflammatory cytokine activity, increased corticosteroid and catecholamine release, resistance to insulin and other growth hormones, bed rest and no or reduced food intake pave the way for a fast decline of body energy and nutrient stores. Such patients need to have nutrition care plans initiated irrespective of body weight or any anthropometric measurement. There are no agreed objective criteria for malnutrition in the ICU patient, but the obvious catabolic clinical picture always needs to be managed from a nutritional point of view. [Strong Consensus, 97% agreement] 3.2.1.2. DRM without inflammation. Synonym: non-cachectic DRM. DRM without inflammation/non-cachectic DRM is a form of disease-triggered malnutrition in which inflammation is not among the etiologic mechanisms. These alternative mechanisms could include dysphagia resulting from upper digestive obstruc- tion, neurologic disorders such as stroke, Parkinson's disease, amyotrophic lateral sclerosis (ALS) or dementia/cognitive dysfunction. Psychiatric conditions like anorexia nervosa and some of the described diseases be involved in the initial phase of the malnutrition trajectory, but does not have a clinically relevant impact in the later phases of the malnutrition process. For some diseases, e.g. Crohn's disease, patients may oscillate between malnutrition with and without inflammation. Diagnostic criteria for DRM without inflammation/non- cachectic DRM are identical with those for malnutrition, com- bined with an underlying disease but with no biochemical indices of present or recurrent inflammation. [Strong Consensus, 94% agreement] 3.2.1.3. Malnutrition/undernutrition without disease. Synonym: Non- DRM. Whilst DRM is the principal form of malnutrition in affluent societies, hunger is still the principal cause of malnutrition in poor developing countries. Hunger is mainly of non-DRM origin. Within the concept of non-DRM there are also miscellaneous socioeco- nomic/psychological mechanisms operating which are unrelated to depression, or malabsorption due to intestinal disorders such as short bowel syndrome (for example after bowel resection due to mesenteric infarction), are other mechanisms for the development of non-inflammation driven DRM. Advanced ageing per se may contribute to DRM without inflammation by anorexia; denoted “anorexia of ageing” [19] (see Section 3.2.3), that is caused also by , basic definition of malnutrition to aetiology-based diagnoses utrition 36 (2017) 49e64 53 availability of food. As indicated advanced ageingmay contribute to any form of malnutrition/undernutrition. The metabolic phenotype and the principles for treatment of non-DRM are in many respects similar for undernutrition/starva- tion due to hunger, socioeconomic/psychological factors, or DRM without inflammation. [Strong Consensus, 97% agreement] 3.2.1.3.1. Hunger-related malnutrition. Hunger-related malnu- trition is caused by deprivation of food, and is mainly appearing in poor developing countries and can manifest through famine due to natural disasters like droughts or flooding. Diagnostic criteria for hunger-related malnutrition are the same as those for malnutrition when hunger or food deprivation in the absence of disease is the clear cause for the condition. [Strong Consensus, 97% agreement] 3.2.1.3.2. Socioeconomic or psychologic related malnutrition. Non-DRM, other than hunger-related malnutrition as described abovemay emerge during difficult situations such as poverty, social inequities, poor care, mourning, poor dentition, self-neglect, im- prisonments or hunger strike. Such conditions have effect not only on the energy intake, but also on the quality of the food intake. [Strong Consensus, 97% agreement] al N 3.2.2. Sarcopenia Sarcopenia is a syndrome of its own characterized by the pro- gressive and generalised loss of skeletal muscle mass, strength and function (performance) with a consequent risk of adverse out- comes [20e22]. Whilst often a phenomenon of the ageing pro- cesses (primary sarcopenia) preceding the onset of frailty (see below), it may also result from pathogenic mechanisms (secondary sarcopenia) [20] that are disease-related, activity-related (e.g. disuse) or nutrition-related (e.g. protein deficiency). Diagnostic criteria for sarcopenia have not been firmly estab- lished to date. The ESPEN endorsed recommendations of the Eu- ropeanWorking Group on Sarcopenia in Older Persons [20], as well as the statement from the ESPEN Special Interests Groups of Cachexia in Chronic Disease and Nutrition in Geriatrics [16] indicate an algorithm based on loss of muscle mass and strength and/or function. Muscle mass can be estimated by any validated technique, which in clinical practice usually involves dual x-ray absorptiom- etry (DXA), bio-electric impedance analysis (BIA) or computed to- mography (CT) scanning. For example, reduced muscle mass could be indicated by an appendicular skeletal muscle mass index <7.26 kg/m2 (men) and <5.5 kg/m2 (women) [20]. Reduced muscle function may be designated by reduced gait speed or failure of the chair standing tests (which tests lower extremities). Practical diagnostic cut-offs for gait speed are considered to be: <0.8 m/s [20] or <1.0 m/s [21]. Reduced muscle strength may also be measured by handgrip strength; suggested cut-off points are <20 kg for women and <30 kg for men [20]. [Strong Consensus, 94% agreement] 3.2.2.1. Sarcopenic obesity e see section 3.2.4.1.1. , 3.2.3. Frailty The definitionof frailty is evolving, as this emerging concept is still under discussion among experts in gerontology and geriatrics [23]. The general perception is that frailty is a state of vulnerability and non-resilience with limited reserve capacity in major organ systems. This leads to reduced capability towithstand stress such as trauma or disease and thus frailty is a risk factor for dependence and disability. Frailty is mainly related to advanced age but never- theless it is considered to be modifiable by lifestyle interventions. The condition contains nutrition-related components; e.g. weight loss, and is linked to sarcopenia [24]. In that capacity physical frailty merits to be listed among nutrition-related conditions. Anorexia of ageing is an unintentional decline in food intake caused by factors such as altered hormonal and neuro-transmitter balance affecting hunger and satiety whichmay contribute to age-relatedweight loss [19]. Financial constraints, loneliness, depression, difficulties with chewing (including poor dentition) and presbyphagia (changes in the swallowing mechanism) are further examples of conditions that may contribute to malnutrition and thus to frailty in the more elderly. Several sets of diagnostic criteria for physical frailty have been suggested. The phenotype of frailty as defined by Fried et al. [25] included the fulfilment of three out of five criteria: weight loss; exhaustion (fatigue); low physical activity; slowness (e.g. reduced gait speed); and weakness (e.g. low grip strength). Detailed cut-off values for each measurement have been suggested, but consensus is yet not achieved [26]. [Strong Consensus, 97% agreement] 3.2.4. Over-nutrition 3.2.4.1. Overweight and obesity. Overweight and obesity are defined as abnormal or excessive fat accumulation that may impair health [27]. Classification of overweight and obesity in adults is T. Cederholm et al. / Clinic54 achieved through the use of body mass index (BMI), which is a simple index of weight-for-height. It is defined as a person's weight in kilograms divided by the square of their height in meters. Accordingly, - BMI between 25 and 30 kg/m2 implies overweight - BMI greater than or equal to 30 kg/m2 implies obesity Obesity can be further classified in grades according to BMI Obesity grade I: BMI 30 e <35 kg/m2 Obesity grade II: BMI 35 e <40 kg/m2 Obesity grade III: BMI �40 kg/m2 Grading of obesity could be adjusted for race/ethnicity. Thus, corresponding lower cut-offs have been proposed for Asian pop- ulations both for diagnosis of obesity [28,29], and for risk of obesity-associated complications [30]. As previously mentioned in Section 3.2.1.1 it is also common for overweight/obese persons to be malnourished in the setting of disease or injury or consumption of high energy poor quality diets, such that over-nutrition and malnutrition may exist simulta- neously. [Strong Consensus, 94% agreement] 3.2.4.1.1. Sarcopenic obesity. Sarcopenic obesity is defined as obesity in combination with sarcopenia that occurs for example in older individuals, in those with T2DM, COPD, and in obese patients with malignant disorders and post organ transplantations. Mech- anisms include inflammation and/or inactivity induced muscle catabolism in obese patients [31,32]. The condition can occur virtually at all ages. For body composition measurement in clinical practice DXA might be most accurate in obese individuals. Computed tomogra- phy (CT) scan is an alternative emerging technology for the mea- surement of muscle mass. There is no clear consensus about normal ranges for fat-freemass index (FFMI, fat-freemass/height2), and the uncertainty is even larger for the obese individual, since the normal ranges might be different from the lean population [33]. Low FFMI and high FMI was associated with poor outcome in terms of length of hospital stay when compared with normal FFMI or FMI, when using BIA in a large cohort of hospital patients [34]. Currently, there are no commonly accepted criteria for sarco- penic obesity beyond those for sarcopenia and obesity separately. Muscle function can be assessed by strength and power as for sarcopenia, i.e. muscle strength by using hand grip measurements or chair stand tests. Muscle power could be measured by gait speed, or by assessing patient autonomy by Activity of Daily Living (ADL) scores andmobility by for example the Short Physical Performance Battery (SPPB) [35].

Accumulation of intraabdominal fat is associated with higher metabolic and cardiovascular disease risk [27], which includes insulin resistance, T2DM, dyslipidaemia and hypertension. These associations are most relevant in moderately obese patients (BMI<35) as well as in non-obese individuals cate- gorized as overweight (i.e. with BMI 25- 30). The presence of cen- tral obesity (also known as abdominal, visceral, upper-body or android obesity) can be clinically defined by increased waist circumference (WC) measured in the mid-horizontal plane be- tween the superior iliac crest and the lower margin of the last rib [36]. Recent European consensus statements define abdominal obesity by WC �94 cm for men, and �80 cm for women [37], whereas US Guidelines indicate corresponding definitions of �102 cm and �88 cm respectively [38]. Like for obesity ethnic and regionally adapted cut-offs are also available. Intraabdominal fat can also be assessed by imaging techniques utrition 36 (2017) 49e64 but these are costly and not routinely available, and in addition al N there are no clearly defined values for assessment. [Strong Consensus, 97% agreement] 3.2.5. Micronutrient abnormalities Micronutrient abnormalities can involve a deficiency or excess of one or more vitamins, trace elements or minerals. Abnormalities may result from changes in food intake, absorption, losses, re- quirements and intake of medicines, alone or in combinations. In- dividual requirements can vary according to age and diet (foods may be fortified) as well as the presence of disease or injury. A complete nutritional assessment is important when assessing micronutrient status since specific micronutrient deficiencies are frequently associated with undernutrition [39]. Analysis of dietary records may suggest potential deficiency or excess based on rec- ommended dietary allowances (RDA). RDAs are defined for healthy populations and may therefore not always match the needs of in- dividuals with disease. The laboratory assessment of micronutrient abnormalities is complex since measured concentrations do not necessarily reflect adequacy, for example an acute phase response can affect the concentration reported. Laboratory testing of micronutrient status is generally not routinely undertaken unless there is a specific acute concern, use of restrictive dietary regimes, a prolonged history of undernutrition or during supplementation. [Strong Consensus, 100% agreement] 3.2.5.1. Micronutrient deficiency. Micronutrient deficiency occurs when there is a deficit of one or more micronutrient/s compared to requirements [40]. Specific micronutrient deficiencies can have dramatic consequences such as rickets and osteoporosis from vitamin D deficiency, night blindness from vitamin A deficiency, or beriberi or Wernicke-Korsakov syndrome due to thiamine deple- tion. But micronutrient deficiencies can also lead to impaired function that may be less obvious such as poor wound healing or increased susceptibility to infection. These more subtle effects may be overlooked in clinical practice, for example after bariatric sur- gery [41]. Laboratory assessed concentrations may be valuable when there is concern about long-standing deficiency following clinical assessment or when infrequent periodic checks are required for long-term nutritional supplementation. [Strong Consensus, 94% agreement]3.2.5.2. Micronutrient excess. Micronutrient excess occurs when there is too much of one or more micronutrients compared to re- quirements [42]. Micronutrient excess can lead to specific symp- toms such as the movement disorders of manganese accumulation and subsequent toxicity, or to more general symptoms such as skin irritation and rashes from excessive niacin, hip fracture risk ensuing from excessive retinol intake or peripheral neuropathy following long lasting high intake of vitamin B6. Overprovision of micro- nutrients can result from incorrect prescription. Clinical assessment and diagnosis play key roles in determining micronutrient excess, partly due to the difficulties with laboratory analyses. For patients on long-term nutritional supplementation laboratory monitoring every 6 months can be recommended [43]. [Strong Consensus, 94% agreement] 3.2.6. Refeeding syndrome Refeeding syndrome (RS) is a severe disruption in electrolyte or fluid balance that is precipitated in malnourished subjects when feeding (oral, enteral or parenteral nutrition) is begun too aggres- sively after a period of inadequate nutrition. Patients at high risk are those with chronic alcoholism, subjects with severe chronic un- T. Cederholm et al. / Clinic dernutrition, anorexia nervosa, or depleted patients with acute illness. Clinical symptoms can include fluid retention with pe- ripheral oedema, congestive heart failure, cardiac arrhythmia, res- piratory failure, delirium, encephalopathy, and other severe organ dysfunctions. RS usually occurs within the first four days after nutrition therapy is commenced. Hypophosphatemia that drives many of the medical complications of RS may be the most frequent electrolyte disturbance, with or without hypokalaemia, hypomag- nesemia and hypocalcaemia [44]. Diagnostic criteria for RS include fluid imbalance, disturbed glucose homeostasis, hyperlactatemia suggesting vitamin B1 defi- ciency, but most frequently hypophosphatemia, hypomagnesemia and hypokalaemia. Screening for patients at risk of RS includes one or more of the following: BMI<16 kg/m2; unintentional weight loss >15% in 3e6 months; little or no intake for >10 days; or low po- tassium, phosphate and magnesium before feeding. If two or more of the following factors exist a risk of RS should also be considered: BMI <18.5 kg/m2; unintentional weight loss >10% in 3e6 months; little or no nutritional intake for >5 days; or a history of alcohol misuse or chronic drug use (insulin, antacids, diuretics) [43,45]. [Strong Consensus, 97% agreement] 3.3. Nutritional procedures - the nutrition care process Nutritional care should be provided in a systematic sequence that involves distinct interrelated steps and this systematic sequence is called a nutrition care process (Table 5). 3.3.1. Malnutrition risk screening Risk screening is a rapid process performed to identify subjects at nutritional risk, and should be performed using an appropriate validated tool in all subjects that come in contact with healthcare services. Depending on the care setting, screening should be per- formed within the first 24e48 h after first contact and thereafter at regular intervals. Subjects identified as at risk need to undergo nutritional assessment (see Section 3.3.2). There are several risk screening tools in use, and many are validated for predicting outcome, whereas some identify subjects that will benefit from nutrition therapy. It is important to underscore that “risk of malnutrition” as it is identified by the screening tools (usually combining weight loss, reduced food intake and disease activity) is in itself a condition related to increased morbidity and mortality. ESPEN suggests the use of Nutrition Risk Screening-2002 (NRS- 2002) and the Malnutrition Universal Screening Tool (MUST). For older persons ESPEN recommends the use of the Mini Nutritional Assessment (MNA) either in its full or short form (MNA-SF). These tools are all compiled of various combinations of registered or measured BMI, weight loss, food intake, disease severity and age. Other validated tools that combine similar variables and which are frequently used include the Malnutrition Screening Tool (MST) and the Short Nutritional Assessment Questionnaire (SNAQ). Malnu- trition risk screening tools are well described in the literature and will not be further described here [46e50]. [Strong Consensus, 97% agreement] 3.3.1.1. Pre-cachexia screening. The process to screen for pre- cachexia, a state that may precede cachexia, is performed in or- der to launch measures that may prevent or postpone the devel- opment of cachexia as early as possible. The procedure refers mainly but not exclusively to patients with cancer [16], and could be regarded as a form of DRM with inflammation risk screening procedure (see Section 3.3.1). Pre-cachexia is diagnosed in patients affected by chronic dis- eases, including cancer, based on the concomitant presence of utrition 36 (2017) 49e64 55 weight loss <5%, anorexia and metabolic disturbances related to systemic inflammation as revealed by for example increased serum CRP levels [16,17]. [Strong Consensus, 97% agreement] 3.3.1.2. Sarcopenia screening. The ESPEN endorsed statement from the European Working Group on Sarcopenia in Older Persons rec- ommends screening for sarcopenia from age 65 years onwards by measuring gait speed and then, based on the results handgrip strength and/or muscle mass [20].

Predefined assess- � Instructions for implementing the specified form of nutrition - Biochemistry: There are no good biochemical markers of the T. Cederholm et al. / Clinical N56 ment tools like Subjective Global Assessment (SGA) [51], Patient- Generated (PG)SGA and Mini Nutritional Assessment (MNA) could be used to facilitate the assessment procedure. Assessment of the nutritional status comprehends information on body weight, body height, body mass index (kg/m2), body composition (see Section 3.3.6.2) and biochemical indices (see Section 3.3.6.3). [Strong Consensus, 97% agreement] Objectives of the assessment are to evaluate the subject at risk according to the following measures: - A medical history should be taken, and physical examinations and biochemical analyses should be performed in order to decide the underlying disease or condition that may cause the potential state of malnutrition. - Social and psychological history is taken to establish potential effects of living conditions, loneliness and depression on nutri- tional needs, and whether input from other professional groups may be of benefit. - A nutrition history, including limitations in food intake, should be taken and examinations and observations should be per- formed in order to decide the underlying nutritional causes, and to identify major nutritional obstacles and calculate nutritional needs. - Energy and fluid needs are determined by indirect calorimetry (energy expenditure) or calculated according to validated equations. - Protein needs are established in the range from 0.8 g/kg/day (healthy adults) and up to 1.5 g/kg/day (in some cases even higher) according to age, disease and degree of protein deple- tion [52]. - Micronutrient needs should be determined according to pre- vailing recommendations and the clinical picture. [Strong Consensus, 94% agreement] 3.3.3. Diagnostic procedure When the nutrition risk screening identifies subjects at risk, the nutritional assessment will provide the basis for the diagnosis of Table 5 The nutrition care process. � Malnutrition risk screening � Nutritional assessment � Diagnostic procedure � Nutritional care plan � Nutritional care ➢ Nutrition therapy � Monitoring and evaluating the effects of nutritionalcare and therapy � Documentation 3.3.2. Nutritional assessment Nutritional assessment should be performed in all subjects identified as being at risk by nutritional risk screening, andwill give [Strong Consensus, 97% agreement] nutritional status. Plasma albumin and transthyretin/pre- albumin concentrations may be used mainly to indicate and monitor catabolic activity. Their validity as nutrition indicators is low in view of their perturbation by inflammation. - Function: e.g. hand grip strength (HGS), chair rise tests and gait speed, either alone or combined in the Short Physical Perfor- 3.3.5.1. Nutrition therapy. Nutrition therapy describes how nutri- ents are provided to treat any nutritional-related condition. Nutrition or nutrients can be provided orally (regular diet, thera- peutic diet, e.g. fortified food, oral nutritional supplements), via enteral tube-feeding or as parenteral nutrition to prevent or treat malnutrition in an individualized way. [Strong Consensus, 97% agreement] 3.3.6. Monitoring Monitoring of nutrition therapy is a measure to check and adjust that nutrition delivery is in progress and nutrition intake or pro- vision is sufficient, as well as to assure tolerance and that goals and expected outcomes are achieved. The monitoring procedures require an individual plan where nutrition goals are defined. [Strong Consensus, 97% agreement] Fact Box: Monitoring plan of nutritional care and therapy. - Nutrition provision and intake: Are calculated requirements of fluid, energy and protein met? - Weight, anthropometry, body composition: Does e.g. weight, fat free mass (FFM) or fat mass (FM) change as expected? 3.3.5.

This part of the assessment procedure is often neglected, mainly due to the absence of a global consensus for diagnostic criteria and their cut-offs [7e9]. [Strong Consensus, 97% agreement] 3.3.4. Nutritional care plan The nutritional care plan is a scheme for nutrition therapy based on the results of the assessment. This plan should be developed by a multi/interdisciplinary team together with the patient and his/her carer in order to achieve patient centered treatment goals. A comprehensive nutritional care plan defines the rationale, explains the nutrition therapy and provides suggestions for monitoring the efficacy of the plan and reassessment. The nutritional care plan includes information on: � Energy, nutrient and fluid requirements � Measureable nutrition goals (immediate and long-term) utrition 36 (2017) 49e64 mance Battery (SPPB) [35] could be used. al N - Quality of life (QoL): e.g. EQ-5D or HRQOL, or other tools rele- vant to the diagnosis, could be used. It should be emphasized that current biochemistry, functional and QoL measurements may not be sensitive enough to capture relevant changes of the nutritional status. [Strong Consensus, 97% agreement] 3.3.6.1. Nutrition intake. In the hospital setting, recording of nutrition intake can be performed at the bedside by nurses or as- sistant nurses, using plate diagram sheets that have proven clini- cally useful [53,54], or using self-recorded diary by patients themselves [55]. Amount of food consumption could be estimated by food records during 2e4 days [56,57]. Food weight record, i.e. to weigh each food item before and after food consumption, is difficult to implement in clinical practice, but is often used in research. Modern digital technologies may provide new means to establish food intake [58]. [Strong Consensus, 100% agreement] 3.3.6.2. Weight and body composition. Monitoring of weight during hospitalization may not be sensitive due to disease or therapy related shifts in fluid balance. Nevertheless, weight should be recorded one to three times per week whilst a patient is in hospital with a decreasing frequency when in a stable condition. If the pa- tient is undergoing ambulatory treatment the type of underlying condition will indicate the interval of weight measurement required. Regular weight measurements are not useful for patients in late palliative phases, or in any subject at end of life. FFM and FM are estimated by bio-impedance analysis (BIA) or DXA-scan, but subject to the same limitations as weight measurements. Standard anthropometric measurements, such as mid-arm-circumference, calf-circumference or skinfold thickness are potential alternatives although subject to measurement variability [59]. [Strong Consensus, 93% agreement] BIA is a quick non-invasive method to estimate body composi- tion, but requires stringent standard procedures such as a fast for at least 2 h and urination before the test is carried out [60,61]. Single frequency-BIA (SF-BIA) is commonly used to estimate total body water (TBW) and fat free mass (FFM) with a validated formula. Multi frequency-BIA (MFBIA) and bioelectrical impedance spec- troscopy (BIS) calculate intracellular water (ICW), extracellular water (ECW), TBWand FFM. BIS offers information of ICWand ECW distribution. From these FFM is predicted. BIA-derived phase angle has a strong prognostic value [62]. [Strong Consensus, 97% agreement] DXA is regarded as a more accurate method on an individual level. It is an accepted reference method to evaluate BIS. DXA gives information on FM, lean soft tissue (LST) and bone mineral content (BMC). The radiation dose of a single DEXA measurement is dependent on the device and the age of the patient, but is low and therefore the expected lifetime risk of fatal cancer is negligible. However, DEXA is not recommended for pregnant women. [Strong Consensus, 100% agreement] Computerized tomography (CT) imaging is being increasingly used to evaluate muscle mass depletion [63]. CT scanning is often performed in patients with malignant disorders, thus providing images that could be used for the evaluation of muscle mass. The fact that reference values are scarce for this technique will reduce its validity until such data are available. [Strong Consensus, 97% agreement] 3.3.6.3. Biochemical indices. Biochemical markers, e.g. serum con- centrations of visceral proteins, should not be used as indicators of a patient's nutritional status. Monitoring visceral protein levels T. Cederholm et al. / Clinic during refeeding in DRM with inflammation may be helpful, keeping in mind that variations are reflecting the degree of catab- olism/inflammation rather than nutritional recovery [64]. Under some circumstances, and taking into account each protein's half- life, levels of albumin (T½ 21 days) and transthyretin/prealbumin (T½ 3 days) may be monitored for long- and short-term effects [65]. Especially in severely malnourished subjects where inflammation is not present, visceral protein levels may improve with nutritional resuscitation [64]. C-reactive protein serum concentrations are suggested for monitoring inflammatory activity (see also Section 3.2.1.1.1). [Strong Consensus, 100% agreement] 3.3.6.4. Physical function. Measurement of physical function is crude, but nevertheless a relevant way to monitor nutritional care and therapy. Hand grip strength by a hand held dynamometer, gait speed or chair rise tests are fairly easy to undertake for the mea- surement of changes in muscle function sensitive to nutrition in- terventions [66e68].Composite functional scores, like the Short Physical Performance Battery (SPPB) [35], De Morton Mobility In- dex [69] or the Barthel Index [70] may also be relevant functional measures. [Strong Consensus, 100% agreement] 3.3.6.5. Quality of life. Health related quality of life assessed by a validated tool; e.g. EQ-5D [71] may be used as a crude non-specific measure of changes in nutritional status, and as an indicator of reduced food intake [72]. [Strong Consensus, 97% agreement] 3.3.7. Documentation Nutritional care given has to be communicated at discharge from a healthcare facility to the next caregiver in order to secure continuation of the nutritional care and support. Documentation in medical, dietetic and care records should be provided for nutritional risk screening, diagnosis, assessment of risk factors, nutritional requirements, nutrition therapy, goals and outcomes for nutrition therapy, including estimated time to reach goals, as well a note of who is responsible for the follow-up [73]. The documen- tation should also provide information on need for help for servings and eating, need for oral care and which are the preferred meals [74] [Strong Consensus, 100% agreement] 3.4. Organization of nutritional care at hospitals and care facilities Nutritional care in some form is provided to all patients within a hospital or care facility. Depending on the type and severity of the nutritional problems of the patients, the structure and organization of the nutritional care needs to be adapted (Table 6). 3.4.1. Care catering (hospital catering) Care catering or hospital catering is the provision of menu ser- vices (in-house or outsourced) in health care facilities. The mini- mum requirements of hospital and care catering are to serve a variety of foods that are suitable and adapted to all types of patients with a variety of energy and nutrient densities. Special diets, food texture, allergies and specific cultural aspects have to be considered at all times. For patients with, or at risk, for malnutrition, informed choices with respect to food items and portion sizes have to be ensured. Twenty-four-hour access to nutritionally relevant and well-prepared food should be mandatory, and served portions must appear appetizing for the individual. Energy dense small size portions should be available as an option for patients at nutritional risk. [Strong Consensus, 97% agreement] 3.4.2. Nutrition steering committee (NSC) A NSC is a committee at a hospital or care facility of a mixed interdisciplinary composition including directors, managers, health utrition 36 (2017) 49e64 57 professionals and catering staff. The main objective of a NSC is to set standards for the structure, procedures and management of clinical nutrition at the relevant institutions. Depending on the legal status of the NSC (mainly decided by the care facility management) it may also be responsible for the audit of the nutritional care and responding to nutritional incidents. [Strong Consensus, 97% agreement] 3.4.3. Nutrition support team (NST) problems. Moreover, the objective includes ensuring that all focussed teams linked to specific care facilities could also be objective to serve and support the staff as well as individual pa- T. Cederholm et al. / Clinical N58 Table 6 Organizational forms of providing nutritional care and support. � Care catering/Hospital catering � Nutrition Steering Committee � Nutrition Support Team � Disease-specific Support Teams � Clinical Nutrition Care Unit � Clinical Nutrition Support Unit tients according to nutritional issues. Hospital dietitians could be organized in independent administrative units, or be formally in- tegrated parts of the multi-disciplinary team at department level. [Strong Consensus, 93% agreement] 3.4.6. Clinical nutrition support unit Based on hospital's organization, patients that require nutrition therapy or receive home artificial/medical nutrition who develop complications such as central line infection can be hospitalized in specific clinical nutrition support wards managed by a multidisci- plinary team of specialized physicians, nurses, dietitians and pharmacists. [Strong Consensus, 93% agreement] available. For example, an Obesity team is a multidisciplinary team of specialists consisting of physicians, dietitians, nurses, physio- therapists, behavioural therapist (psychologist/psychiatrist) as well as other relevant professionals. The Obesity team provides personalized, patient-centred and comprehensive weight man- agement/lifestyle programmes which take into account the comorbidities of the obese patients. The Obesity team should also assist “bariatric surgery” services for pre- and post-operative care. Similar team approaches are relevant for example for diabetes, chronic obstructive pulmonary disease, cancer and palliative care. [Strong Consensus, 100% agreement] 3.4.5. Clinical nutrition care unit In many hospitals across different countries, dietitians represent a core of nutrition professionals at the hospital, with the specific nutrition therapy utilises state-of-the-art knowledge and tech- niques to prevent and treat disease-related malnutrition of both inpatients and out-patients [75]. [Strong Consensus, 97% agreement] 3.4.4. Obesity and other disease-specific support teams In addition to Nutrition Support Teams (NSTs) that usually works across all hospital departments, disease or condition A NST is a multi-disciplinary team of physicians, dietitians, nurses and pharmacists. Other relevant professionals may also be part of the NST, e.g. physiotherapist and speech therapists. The main objective of the NST is to support hospital staff in the provision of nutrition therapy, especially enteral or parenteral nutrition, to ensure that the nutritional needs of patients are satisfied, especially for those patients with complicated nutritional [Strong Consensus, 97% agreement] 3.5. Forms of nutritional care Nutrition care and therapy can be provided in many ways (Table 7). 3.5.1. Meal environment 3.5.1.1. Meal support. Meal support is specific efforts to promote food intake, which encompasses friendly social interactions with the caring staff as well as with other patients or residents during mealtimes. Suitable meal-time ambiance contributes to a relaxed and comfortable environment. The atmosphere or the perception of the entirety of the meal is the product of both material and immaterial factors. Protected mealtimes, i.e. not allowing medical or caring procedures to take place during themeal, is a further meal support action to promote oral intake [76,77]. Patients' choice from a la carte menus and meals-on-demand are increasingly offered [78]. [Strong Consensus, 100% agreement] 3.5.1.2. Eating support. Eating support encompasses actions to enable an individual to eat through verbal encouragement and physical support. Eating support prioritizes a number of factors such as positioning at the table, provision of assistive eating tools, assistance with cutting the food in smaller pieces, and helping patients to make informed food choices [76,79]. [Strong Consensus, 100% agreement] 3.5.2. Diets Dietary advice and counselling about food choices and prepa- rations may be relevant for patients, relatives and informal care- givers concerning all below described types of diets. 3.5.2.1. Regular hospital diet. Regular hospital diet should cover individual patient's nutrient and energy requirements according to recommendations based on scientific evidence. Diet composition takes local food habits and food patterns into account as long as there are no specific therapeutic requirements, in which cases a therapeutic diet or functional food is required (see below). [Strong Consensus, 97% agreement] 3.5.2.1.1. Food product. A food product is any food that is suit- able for human consumption whichprovides energy-containing macronutrients (e.g. carbohydrates, protein, fats), and/or micro- nutrients (e.g. vitamins, minerals), and/or other substances which may contribute to fulfil the nutritional requirements of the patient. [Strong Consensus, 100% agreement] 3.5.2.2. Therapeutic diet. Therapeutic diets are prescribed accord- ing to the specific need of the patient. 3.5.2.2.1. Food modification. Some conditions or disorders, e.g. diabetes mellitus, hyperlipidaemia, hepatic encephalopathy, renal or celiac disease may require food modifications that could include adjustments of carbohydrate, fat, protein and micronutrient intake, or the avoidance of specific allergens. [Strong Consensus, 97% agreement] 3.5.2.2.2. Fortified food. Fortified food is food products to which vitamins, minerals, energy or other nutrients, or a combination of them, have been added to increase energy or nutrient density. [Strong Consensus, 97% agreement] 3.5.2.2.3. Food supplements. Food supplements are food prod- ucts that supplement normal diet and which are concentrated sources of nutrients (e.g. vitamins or minerals) or other substances with a nutritional or physiological effect, alone or in combination, marketed in various dose forms: capsules, tablets and similar forms, sachets of powder, ampoules of liquids, drop dispensing bottles, and other similar forms oral dosage forms, liquids and utrition 36 (2017) 49e64 powders designed to be taken in measured small unit quantities (https://www.efsa.europa.eu/en/topics/topic/supplements). [Strong Consensus, 100% agreement] 3.5.2.2.4. Functional food. Functional food is food fortified with additional ingredients or with nutrients or components intended to yield specific beneficial health effects. [Strong Consensus, 100% agreement] 3.5.2.2.5. Texture modified food and thickened fluids. Texture modified food and thickened fluids can be available in several various qualities. Although there are no harmonised de- scriptors they could be described as follows [80]: - Liquidized/thin pur�ee; Homogenous consistency that does not hold its shape after serving. - Thick pur�ee/soft and smooth; Thickened, homogenous consis- tency that holds its shape after serving and does not separate into liquid and solid component during swallowing, i.e., cohesive. - Finely minced; Soft diet of cohesive, consistent textures requiring some chewing (particle size most often described as 0.5 � 0.5 cm). - Modified normal; Normal foods of varied textures that require chewing, avoiding particulate foods that pose a choking hazard (particle size most often described as 1.5 � 1.5 cm).

Medical nutrition therapy Medical nutrition therapy is a term that encompasses oral nutritional supplements, enteral tube feeding (enteral nutrition) and parenteral nutrition. The two latter has traditionally been called artificial nutrition, but this term is suggested to be replaced by medical nutrition therapy. Nutrition products that are delivered via the gastrointestinal tract, i.e. provided orally or as tube feeding, are defined in the EU legislation as “foods for special medical purposes” (FSMPs) (Directive on foodstuffs intended for PARticular NUTritional useS 2009/39/EC 2013/609/EC (PARNUTS) [81,82]. FSMPs are defined as “specially processed or formulated and intended for the dietary [Strong Consensus, 96% agreement] management of patients, including infants, to be used under medical supervision; it is intended for the exclusive or partial feeding of patients with a limited, impaired or disturbed capacity to take, digest, absorb, metabolise or excrete ordinary food or certain nutrients contained therein, or metabolites, or with other medically-determined nutrient requirements, whose dietary management cannot be achieved by modification of the normal diet alone” - Regulation (EU) no 609/2013 of the European parlia- ment and of the council. The PARNUTS directive will be replaced by the FSG regulation 2013 (Regulation on Food for Specific Groups), supplemented by delegated regulation (EU) 2016/128 on FSMP. [Strong Consensus, 100% agreement] 3.5.3.1. Oral nutrition therapy. Oral nutrition therapy is mainly given as oral nutritional supplements (ONS) and defined as FSMP (see above). ONS are developed to provide energy and nutrient- dense solutions that are provided as ready to drink liquids, cr�emes or powder supplements that can be prepared as drinks or added to drinks and foods. Liquid ONS (either ready to drink or made up from powders) are sometimes referred to as sip feeds. Clinical effects and cost-effectiveness are well established [83e85]. [Strong Consensus, 97% agreement] 3.5.3.2. Enteral tube feeding. Synonym: enteral nutrition. Enteral tube feeding is nutrition therapy given via a tube or stoma into the intestinal tract distal to the oral cavity. Enteral formulas are defined as FSMP (see above). The tube could be inserted via the nose; i.e. naso-gastric, naso-jejunal or naso-post pyloric tube feeding; or via a stoma that is inserted endoscopically into the stomach; i.e. percutaneous endoscopic gastrostomy (PEG) or with a jejunal extension (PEG-J) or into the jejunum (percutaneous endoscopic jejunostomy (PEJ)). Finally, the tube may also be placed surgically; i.e. surgical gastrostomy or jejunostomy. [Strong Consensus, 97% agreement] 3.5.3.2.1. Total enteral tube feeding. Synonym: total enteral nutrition (TEN). Total enteral tube feeding (TEN) refers to condi- tions when all nutrient needs are provided through a feeding tube without significant oral or parenteral intake. [Strong Consensus, 97% agreement] 3.5.3.2.2. Supplemental enteral tube feeding. Supplemental enteral tube feeding is nutrition given to patients whose oral intake of food and fluids is inadequate for reaching their defined target alone. [Strong Consensus, 97% agreement] 3.5.3.2.3. Home enteral tube feeding. Synonym: Home Enteral Nutrition (HEN). When enteral tube feeing is used outside the hospital it is called Home Enteral Nutrition (HEN) or as in some countries Home Enteral Tube Feeding (HETF). It can be provided either as total or supplemental enteral nutrition. [Strong Consensus, 100% agreement] 3.5.3.3. Parenteral nutrition (PN) therapy. Parenteral nutrition is a type of nutrition therapy provided through intravenous adminis- tration of nutrients such as amino acids, glucose, lipids, electrolytes, vitamins and trace elements. PN can be central through a central venous line, or peripheral through a peripheral intravenous line. [Strong Consensus, 97% agreement] 3.5.3.3.1. Total parenteral nutrition (TPN). Synonym: exclusive parenteral nutrition. Total parenteral nutrition (exclusive paren- teral nutrition) therapy refers to situations where the patient's complete nutritional needs (all macro and micro-nutrients) are covered by the PN, and in which nutrition is not given by any route other than intravenously. [Strong Consensus, 100% agreement] 3.5.3.3.2. Supplemental parenteral nutrition (SPN). Synonym: partial parenteral nutrition or complementary parenteral nutrition. utrition 36 (2017) 49e64 59 Supplemental (partial or complementary) parenteral nutrition al N refersto situations where nutrition is provided in addition to parenteral nutrition by any route other than intravenously. For example, this situation may arise when the oral or enteral tube routes cannot independently achieve the defined nutritional care plan target (See Section 3.3.4). [Strong Consensus, 100% agreement] 3.5.3.3.3. Home Parenteral Nutrition. When parenteral nutrition is used outside the hospital it is called Home Parenteral Nutrition (HPN). HPN used as TPN or SPN is often used for patients with chronic intestinal failure, malignant obstruction or partial obstruction of the gastrointestinal tract [86]. [Strong Consensus, 100% agreement] 3.5.3.3.4. Subcutaneous fluid therapy. The subcutaneous route is a special parenteral route primarily used to provide fluids (hypo- dermoclysis). It can also be used to provide limited amounts of glucose and amino acids, when the intravenous route is unavailable or unsuitable. It is mainly used in late life care. [Consensus, 87% agreement] 3.5.3.3.5. Intra-dialytic parenteral nutrition (IDPN). IDPN is PN given intravenously through the venous line of the dialysis circuit, and thus given cyclic during the dialysis session [87]. IDPN is not a routine technique for supplemental nutrition therapy, but may be indicated to prevent nutritional deterioration in patients receiving dialysis treatment when other methods of nutrition therapy have proved insufficient to meet nutritional and metabolic needs [88]. [Strong Consensus, 97% agreement] 3.5.4. Palliative nutrition Palliative nutrition is the form of nutritional care and therapy that is provided to patients in late phases of end-stage disease. The major goal is to improve quality of life [89]. Food or nutrient re- strictions are avoided. The nutrition measures are decided by the palliative phase. In the early phase energy, proteins and nutrients are provided by the best feasible route. In late phase of palliative care psycho-social support around meals and food intake for both the patient and relatives is prioritized. Parenteral nutrition could be considered to reduce stress around the meal situation. Monitoring of the nutritional status, e.g. recording weight changes, should be avoided to not addmore stress during the final phase of life. [Strong Consensus, 94% agreement] 3.6. Nutritional products for medical nutrition therapy 3.6.1. Oral nutritional supplements (ONS) There are two major types of ONS; those that are nutritionally complete and those that are nutritionally incomplete. 3.6.1.1. Nutritionally complete ONS. These are standard ONS that can be used as the sole source of nourishment for prolonged pe- riods since they have a balanced nutritional composition of macro- and micronutrients, including essential amino acids, essential fatty acids and micronutrients that reflect dietary recommendations for healthy people. They are commonly used as a supplement to the general diet, when the regular food intake is insufficient. Nutri- tionally complete standard ONS can in some cases represent the only source of intake of energy and nutrients. [Strong Consensus, 100% agreement] 3.6.1.2. Nutritionally incomplete ONS. These are not suitable for use as the sole source of nutrients since they are adapted to contain some specific nutrients in higher amounts, whereas the content of other nutrients is lacking or insufficient. Disease-specific ONS are modified in order to meet specific nutritional andmetabolic demands for certain diseases for example T. Cederholm et al. / Clinic60 diabetes, pressure ulcers, cirrhosis, cancer, renal failure and pulmonary disease, and can be complete or incomplete. [Strong Consensus, 94% agreement] 3.6.2. Enteral formulas Standard enteral formulas have a composition that meets the nutritional needs of the general population. In general, energy, protein and micronutrient needs are covered by 1.5 L of standard enteral formula. They can have a standard nutrient profile or can be nutrient adapted for certain conditions or diseases. Most standard enteral formulas (and their high energy and high protein variants) contain fibre and are free of lactose and gluten. Whole protein formulas contain intact proteins, and typically contain lipids that are mostly provided in the form of long chain triglycerides, and carbohydrates that come predominantly as polysaccharides, e.g. maltodextrin. Enteral formulas are mostly nutritionally complete. Formulas containing peptides and medium chain triglycerides can facilitate absorption in case of e.g. malabsorption or short bowel syndrome. Disease specific enteral formulas are designed to meet specific nutritional and metabolic demands, for example for patients with diabetes, pressure ulcers, cirrhosis, cancer, renal failure and pul- monary disease. [Strong Consensus, 94% agreement] 3.6.3. Parenteral solutions Parenteral solutions are composed of carbohydrates (glucose), lipids and amino acids and can include electrolytes, vitamins and trace elements as required. They are defined by the relative composition of the macronutrients, osmolarity, pH and calorie content. These solutions can be administered using separate bottles but are preferably administered using compounding or ready to mix bags. [Strong Consensus, 94% agreement] 3.6.3.1. Parenteral nutrition. Parenteral nutrition infusates for parenteral administration are intended to provide energy and nu- trients, rather than hydration alone. They are usually given intra- venously. PN infusates can aim to provide a single group of nutrients (e.g. the use of lipid emulsion alone) or a combination of nutrients that is more typically thought of as a PN infusate (e.g. a combination of amino acids, glucose, lipid emulsion, electrolytes and vitamins and trace elements in Water for Injection). [Strong Consensus, 93% agreement] 3.6.3.1.1. Three chamber bag/all-in-one PN. A three chamber bag (usually industry manufactured) or all-in-one (mainly pharmacy provided) PN infusate is an emulsion in which amino acids, glucose and lipid emulsion are combined in a single infusate, along with electrolytes, vitamins and trace elements as required. Three-chamber bags contain all macronutrients and electrolytes in three separate compartments. The substrates are mixed together immediately prior to intravenous application by breaking the separation seals between the bag chambers. Three chamber bags are available with or without basic electrolytes. Vitamins and trace elements are injected into the bag prior to administration. This can be a relatively safe system for PN administration, e.g. the risk of infection is lowered by the closed system and by reduced manipulation. Individually compounded all-in-one (AIO) admixtures allow for the provision of patient-specific ready-to-use PN infusates, adapted according to energy, volume and substrate needs. These are asep- tically manufactured from various components, usually in hospital pharmacies, and are designed for immediate intravenous admin- istration, with no mixing or admixing required prior to adminis- tration. These bags are usually compounded daily or weekly due to their often limited stability. They require appropriate storage under utrition 36 (2017) 49e64 refrigeration at 2e8 �C prior to use, but should be gently warmed to types of container (e.g. glass or plastic), or with the intended tion/undernutrition [7]. A similar measure to define diagnostic al N electrolyte available as different salts. These differences lead to a number of considerations such as potential container contami- nants, ordering and storage requirements (e.g. in some cases with high strength potassium solutions), conversion between different units, and differences in stability assessment when electrolyte so- lutions are combined with other components (e.g. the use of inor- ganic compared to organic salts).
